The main aesthetic feature of the May 4th literary trend of thought is "harmony".

The literary revolution is an unprecedented great and thorough literary innovation movement in the history of our country, which has brought great innovation and liberation in literary concepts, contents and forms. In terms of literary concept, it denies the traditional view that "words are the product of feudal system" and games are a pastime, and expresses positive life thoughts and responses to the times. In terms of literary content, it embodies the thoughts of democracy and humanity and is full of the awakening spirit of the times. In terms of language and form, it abandons the rigid traditional formats such as classical Chinese, writes in vernacular Chinese, is close to the people, and creates a brand-new modern literary language and literary form that is in line with the world and has national characteristics. It realized the modernization of literature, thus opening the first glorious page of modern literature in China.

Hu Feng tried to make a theoretical integration between the May 4th literary tradition and the left-wing literary norms. He interpreted the May 4th literary tradition as "the creative practice represented by Lu Xun, the socialist realism theory from the Soviet Union and the revolutionary literary movement centered on popularization". In other words, his efforts are to sum up the practical experience of left-wing literature into the May 4th literary tradition and try to unify them.

However, as mentioned above, the relationship between them is a transformational inheritance. For example, the enlightenment education emphasized by the May 4th literature was transformed into "reform education" by the left-wing literature, and the function of "education" was inherited, which is the origin of the political utility of the left-wing literature. (It is worth noting that the May 4th literature is actually the enlightenment education of intellectuals, that is, the enlightenment education of elites to the folk masses, while the left-wing literature advocates the transformation of writers themselves, with the aim of better literary creation and development, thus giving full play to the functions of literature to a greater extent. In this way, the directionality of the two is generally top-down, but the latter is more complicated). Therefore, the agreement between the two is not the later reality to regulate the history of the former, but the influence of the previous history on the later reality.
